# Astrai Code Review

AI-powered code review with intelligent model routing.
Complex logic goes to powerful models. Formatting and style goes to fast, cheap ones. You save 40%+ without sacrificing quality.

## What it does

- **Smart routing for reviews**: Astrai analyzes the diff complexity and routes to the optimal model. A gnarly concurrency bug gets Opus. A missing semicolon gets Haiku. You only pay for the intelligence you need.
- **Structured output**: Every review returns typed issues with file, line number, severity (critical/warning/info), message, and a concrete suggestion.
- **Strictness modes**: Standard catches bugs and logic errors. Strict adds style and best-practice checks. Security mode focuses on vulnerabilities, injection, auth, and data exposure.
- **BYOK (Bring Your Own Keys)**: Your provider API keys stay with you. Astrai decides which model to use, then calls the provider using YOUR key. You pay providers directly.
- **Cost tracking**: Every review response includes the cost and how much you saved vs always using the most expensive model.
- **Local-only mode**: If you only set `ASTRAI_API_KEY` without provider keys, Astrai uses its own hosted models. Still routed intelligently, still cheap.

## Setup

1. Get a free API key at [as-trai.com](https://as-trai.com)
2. Set `ASTRAI_API_KEY` in your environment or skill config
3. Optionally add provider API keys for BYOK routing (e.g. `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`)
4. Run `/review` on any diff or PR

## Usage

```
/review                     Review the current diff (staged changes)
/review --strict            Strict mode: bugs + style + best practices
/review --focus security    Security-focused review (vulns, injection, auth)
/review --file src/auth.py  Review a specific file
```

### Examples

**Basic review of staged changes:**
```
/review
```
Returns issues found in the current diff with severity levels and suggestions.

**Strict review for a PR:**
```
/review --strict
```
